Beam

Thrown on my beam-ends. Driven to my last shift. A ship is
said to be on her beam-ends when she is laid by a heavy gale
completely on her beams or sides. Not unfrequently the only means of
righting her in such a case is to cut away her masts.

On the starboard beam.

A distant point out at sea on the right-hand side, and at right
angles to the keel. On the port beam. A similar point on the
left-hand side.

On the weather beam.

On that side of a ship which faces the wind.

Beam

(of a stag). That part of the head from which the horns
spring. (Anglo-Saxon béam, a tree; the horns are called
branches.)
